It's cold in Boston and nobody knows better than the workers from D'Allessandro Corp. as they brave subzero temperatures to get a job done.
The Morrissey Boulevard Drainage Conduit Project (MBDC) is underway and is directed by the Boston Water and Sewer Commission on behalf of the Massachusetts Water Resources Authority (MWRA) and in conjunction with the Authority's North Dorchester Bay CSO Storage Tunnel (NDBST) Project.
The contract was awarded to D'Allessandro Corporation of Avon, Mass., and work began in September 2006. The major goal of the project is to improve water quality in North Dorchester Bay.
The project has four crews with four or five workers each at the site. Construction equipment includes a CAT 325 excavator, Komatsu 400 excavator, two Komatsu front-end 320 loaders, two John Deere 410 Loader Backhoes, three Western Star tri-axle dump trucks, and a 120-ton link belt crane. J.F. White of Framingham, Mass., is installing the permanent steel sheeting trench support system as a subcontractor.
John Bald, senior project manager, said that the equipment is chosen for reliability and ease of operator performance.
"Each brand has their own strong points," Bauld said. "We choose our machines by personal preferences."
In 2004 The MBDC was included in the Authority's Supplemental Facilities Plan and Environmental Impact Report on the Long-Term Control Plan for North Dorchester Bay and Reserved Channel and is part of the court-ordered cleanup of Boston Harbor.
The MBDC and NDBST will enable the BOS087 outfall located near Mother's Rest to be eliminated. Storm-water flows generated from smaller storms will be conveyed to the NDBST while storm-water flows generated from larger storms will be redirected to the MBDC.
All storm-water flows along Morrissey Boulevard will be conveyed to the MBDC. The existing Department of Conservation and Recreation's outfall in Savin Hill Cove will be replaced by the MBDC.
The project extends from Savin Hill Cove (downstream end) to the State Police barracks on Wm. Day Boulevard (upstream end). The area is characterized by large businesses and educational and cultural institutions with residential neighborhoods in outlying areas.
Construction began with many utility relocations to install the new 12-foot by 12-foot reinforced concrete box culvert. The project started up at the access road to the University of Massachusetts Boston, John F. Kennedy Presidential Library and Museum and Massachusetts Archives/Commonwealth Museum and proceeds northward in the service road past Boston College High School and the Sovereign Bank complex to Mt. Vernon Street. Work will also take place in Mt. Vernon Street, near the JFK/UMass Red Line Station, and in the Bayside Exposition Center parking lot.
Details of the project include: installation of approximately 660 linear feet of 8-foot by 8-foot reinforced concrete storm drain box conduit; furnish and install approximately 100 linear feet of 9-foot by 8-foot reinforced concrete storm drain box conduit; furnish and install approximately 2,810 linear feet of 12-foot by 12-foot reinforced concrete storm drain box conduit; approximately 410 linear feet of reinforced concrete pipe, ductile iron pipe and PVC pipe for storm drain; approximately 1,600 linear feet of PVC pipe for sanitary sewer pipes; relocate approximately 3,530 linear feet of ductile iron cement lined pipe for water main; 460 linear feet of minor drain; furnish and set approximately 21 manholes, three special manholes, six particle separators, and 23 catch basins (type 5 and type 13); modifications to Regulator 087-7; modifications to Special Manhole "D."
As the project progresses, the Commission is committed to working closely with many departments. Some include the Department of Conservation and Recreation, the Mayor's Office, the Boston Public Works Department, the Boston Transportation Department, the Department of Environmental Protection, utilities, state and federal agencies and as well as the abutters. As with any project, coordination helps mitigate many of the short-term construction-related impacts that will be associated with the project.
The Commission also will adhere to all city and state regulations and ordinances governing construction in public roadways. All dust, debris and excavation will be strictly controlled and monitored.
In an effort to streamline and expedite all temporary and permanent roadway resurfacing activity, the Commission will complete all pavement restoration work as part of this project. Similarly, pavement and grounds impacted by this construction on private property will be restored under this contract.
The Commission is committed to a proactive community relations program designed to keep residents, businesses and elected officials informed about the project. The Commission will hold public meetings listing details of the project on the Commission's website, and will meet with business and civic groups and elected officials to provide periodic updates.
Project staff will work closely with businesses, educational and cultural institutions and residents of abutting neighborhoods regarding traffic management issues, such as maintaining access for employees, visitors and students, deliveries, and trash removal.
Project team members are as follows: John Bauld — senior project manager; Matt Casey — project superintendent; Thomas Ritchie III — SEA Consultants project engineer; Bruno Cardarelli — SEA Consultants resident engineer; Irene McSweeney — BWSC project manager; Edward Duggan — senior design engineer; Michael Carroll — Fay, Spofford & Thorndike — project manager — design.
The project is scheduled to be completed by June 2009.
